The cylinder shape overestimates the compliance distances to the side of the
an
tenna. In reality the compliance distances for occupational exposure to
the side, in line with the front of the antenna, is less than 0.15 metres for all
configurations above. For characteristics of an antenna recommended for
ty
pical configurations of RBS 2107, see Table below.

The maximum power fed to the antenna, as a function of the number of carriers
per antenna and the maximum power (including tolerances and transmission
loss) per carrier, for RBS 2107 at 900 MHz and 1800 MHz, are given in Table 6
on page 11.
